Bently Nevada 31000-28-10-00-235-00-02 31000 English Proximity Probe Housing Assemblies

Description

The 31000-28-10-00-235-00-02 is an English proximity probe housing assembly designed for 3300 XL 8 mm proximity probe integration, featuring a built-in connector protector (Option 28) and a 1.0 m probe cable length (Option 10). This assembly provides robust mechanical and environmental protection for proximity transducers, facilitating external access for gap adjustments or probe replacement without requiring machine disassembly. Constructed from high-strength polyphenylene sulfide (PPS) with stainless steel components, this housing adheres to API 670 standards for externally mounted proximity probe housings. The configuration includes no standoff adapter (Option 00) and a probe penetration depth of 235 mm (Option 235), utilizing 3/4-14 NPT mounting threads (Option 02) without auxiliary fittings (Option 00).

Features

• Integrated 3300 XL 8 mm proximity probe with connector protector
• 1.0 m probe cable length
• Polyphenylene sulfide (PPS) housing material for superior corrosion resistance
• Stainless steel internal components
• 235 mm probe penetration depth
• 3/4-14 NPT mounting thread configuration
• Designed for radial vibration and Keyphasor measurements
• API 670 compliant design

Applications

• Radial vibration monitoring on rotating machinery
• Keyphasor measurement and shaft speed detection
• Critical machinery protection in power generation, petrochemical, and oil and gas industries
• Hazardous area environments (when installed with approved transducer systems and I.S. barriers)
